router/printing problems

by Bill Mills-Curran

I have a home network with 2 routers. My 192.168.2.x network has a couple of windows boxes (some wireless) behind a linkSys router. This network feeds to my 192.168.1.x network which connects to the internet through a second router. My linux box (samba print server) is on the 192.168.1.x network and has a static IP. I just moved to this setup when I got Verizon FIOS. (Their wireless router has poor range.) Problem. Since moving, I can't print to the samba-served printer from the windows boxes. I have modified samba to accept connections from the 192.168.2.x machines. Here's my samba log for the machine that tries to print.

Re: [Wlug] DNS and PPP

by Andy Stewart

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI everybody, Upon further investigation, it appears that the dns server is not replying when the palmtx makes its dns request. The dns server does reply to everybody else on my network. I'll have to look at the dnsmasq configuration to see why that might be happening. I turned on logging for dnsmasq, and it definitely receives the query, and it receives a reply from the upstream dns server, but it doesn't send a reply to the palmtx. I turned off the firewalling to see if it was eating the dns reply, but that doesn't seem to be happening. More news later, Andy - -- Andy Stewart, Founder Worcester Linux Users' Group Worcester, MA, USA http://www.wlug.org -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFE5SnOHl0iXDssISsRArkAAJ0cejcUErAjfMGGmnbd4IKN1IrP6gCeKv/R AAPd7HDzK2lR5W2/3REYov0= =2QZu -----END PGP SIGNATURE-----

What about, $ cat /proc/sys/net/ipv4/ip_forward Is it set to "1"? -Jamie

FUSE - sshfs: GOT IT

Re: [Wlug] FUSE??

by freak4uxxx＠gmail.com

>From what I understand, fuse is the lower layer of filesystems such as captive ntfs and shfs. Captive ntfs uses the win32 drivers for ntfs via user space to allow you to write to an ntfs partition. Shfs is one of a few remote via ssh file systems. -Eric -----Original Message----- From: ken jones <kjones(a)ziplink.net> Subj: [Wlug] FUSE?? Date: Sat Aug 12, 2006 11:03 pm Size: 907 bytes To: WLUG Mailing list <wlug(a)mail.wlug.org> Would somebody please explain to me what exactly FUSE does? I succeeded in using fusexmp to mount my root directory into /tmp/fuse2.5.3/example. I also succeeded in unmounting with fusermount -u. I do not understand why I should want to. This all started when I upgraded the kernel and the type ntfs file system on the other half of my dual mounted system refused to "mount". I got distracted into FUSE then remembered to install the matching kernel-module-ntfs below. Now I am again successfully using 'smbmount' to mount ntfs file types. I am running Fedora 2.6.17-1.2142_FC4 with kernel-module-ntfs-2.6.17-1.2142_FC4-2.1.27-0.rr.10.4.i686.rpm What good is FUSE to me? I've Googled till the cows come home, but I do not understand the responses.
